IINTTED STATES ROLLIN HUDSON GLEASON, OF EGAN, DAKOTA TERRITORY, ASSIGNOR TO HIMSELF, H. PALMER FRENCH, AND CHARLES W. FRENCH, ALL OF SAME PLACE.

ADJUSTABLE-PANEL SNOW-FENCE.

SPECIFICATION forming part of Letters Patent No. 329,640, dated November 3, 1885.

Application filed February 2, 1885. Serial No. 154,787. (No model.)

To all whom it may concern:

Be it known that I, RoLLIN H. GLEAsoN, of Egan, in the county of Moody and Territory of Dakota, have invented a new and Iinproved Adjustable Panel Snow Fence, of which the following is a full, clear, and exact description.

The object or" my invention is to provide a new and improved deilector or adjustable 1o panel for snow-fences, which panel adjusts itself automatically according to-the direction from which the wind blows.

The invention consists in the combination, with a pivoted panel, of an arm secured on i5 the same, a vane on the upper end ofthe arm, and a check-bar connected with the bottom of the pivoted panel, and provided with a longitudinal slot, through which a pin passes into one oi' the posts or standards.

Reference is to be had to the accompanying drawings, forming part ot' this specification, in which similar let-ters ot' reference indicate corresponding parts iu both the figures.

Figure l is an end view ot' my improved adjustable-panel snow-fence, parts being in section. Fig. 2 is a face view of the same, parts being broken out.

The panel A, which is suitably braced and Stifened, is provided with end pivots, and is 3o pivoted between two standards, B, in such a manner that it can turn freely on its longitudinal axis. On one of the pivots of the panel A an angle-bar, C, is loosely mounted at its angle, one shank being parallel with the edge ot' the panel, and the other projecting at an angle of forty-tive degrees to the face of the panel, and to which latter shank an arm, D, is secured, having a vane, E, secured to its upper end, the said vane facing in the 4o same direction as the panel. The lower end of the angle-bar C is connected by a pivot, F, with the end of the panel, and on the said pivot is mounted one end of a bar, G, provided at the opposite end with a longitudinal slot, H, through which a pin, J, is passed into a post or standard, B. The panel is erected at the top of a cut, as shown in Fig. 1. When the wind blows in the direction toward the cut-that is, in the direction of the arrow a', Fig. 1-it strikes the vane E and swings it 5o with the bar D up into the vertical position, thereby bringing the panel into the position shown in Fig. l, atan inclination otforty-tive degrees toward the bottom ot' thecut. The snow and wind, striking the inclined panel, are guided down into the cut and out again, whereby all snow is carried out ofthe cut. When the wind blows over the cut in the direction of the arrow b, the wind strikes the vane E and swings it down to an angle of 6o ninety degrees, the panel A being held horizontal, thus permitting the snow to sweep under it. The vane E 'thus regulates the inclination of the panel A accordingl Ato the direction ofthe wind. The bar G limits the rocking movements of the panel.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a snow-fence, the combination, with a pivoted panel, ot' an arm held on the panel, 7o and a vane on the free end ot' the arm, substantially as herein shown and described.

2. In a snow-fence, the combination, with a panel pivoted between the two standards to swing on its horizontal axis, of an arm connected with the panel, a vane on the arm, and of a check-bar for limiting the swinging movcments ofthe panel, substantially as herein shown and described.

8. In a snow-fence, the combination, with a 8o panel pivoted between the two standards, otan arm connected with the panel and projecting at an angle of forty-tive degrees, a vane on the arm, a slotted check-bar connected with the panel, and of a pin passed through a slot S5 in the bar into one ot' the posts, substantially as herein shown and described.

4. In a snow-fence, the combination, with the pivoted panel A, of the angle-bar C, the bar D, the vane E, and the check-bar G, hav- 9o ing a longitudinal slot, H, substantially as herein shown and described.
